The invention discloses a ship position dynamic point inspection method based on a ship track, and the method comprises the following steps: S01, continuously obtaining AIS data and ship archive data to determine data information of ships in a target region, the data information comprising the number of point inspection ships in the region, ship information and space coordinates; s02, data capture in a continuous period is carried out based on each selected ship; s03, capturing the data of the ship through the data, and obtaining a navigation track in a fixed point area; s04, based on a judgment strategy, the state of the ship is judged according to the navigation track; and S05, feeding back the state of the ship to a console. According to the ship position dynamic point inspection method based on the ship track, on the basis of a weighted KNN algorithm, through research and judgment modeling of space-time distance and track similarity, behaviors such as ship opening, return voyage and operation are judged, a ship dynamic point inspection list is generated, and an alarm is given for an abnormal ship.

    本发明公开了一种基于船舶航迹的船位动态点验方法,包括以下步骤:S01、通过连续获取AIS数据和船舶档案数据,以确定目标区域船舶的数据资料,所述数据资料包括区域内点验船舶数量、船舶信息以及空间坐标;S02、基于择定的每一个船舶进行连续周期的数据抓取;S03、通过数据抓取所述船舶的数据,获取定点区域内航行航迹;S04、基于判断策略,根据航行航迹判定所述船舶的状态;S05、将所述船舶的状态反馈至控制台。该发明提供的基于船舶航迹的船位动态点验方法,基于加权KNN算法,通过时空距离和航迹相似度研判建模,判断船舶开航、返航、作业等行为,生成船舶动态点验清单,针对异常船舶进行报警。
